The NBA has opened an investigation into how free agency operated this offseason. The league office heard concerns from owners over the number of deals that were completed during the opening hours of free agency.

Sources tell Zach Lowe and Brian Windhorst that the scope of the investigation is still being determined.

It is technically against league rules for players to tamper with each other and work together on transactions before the opening of free agency. The NBA has previously set a precedent that they wouldn't punish players as it is difficult to police play-to-player communication.

While the NBA may not eventually issue any formal punishment, it could lead to modifications of the free agency system.
